A new study suggests that middle-aged adults recently diagnosed with diabetes
and hypertension have time to try to learn how to control their high blood pressure
without medications, but not too much time.
The consequences of delaying effective hypertension treatment for up to a year were small - a two-day reduction in quality-adjusted life expectancy - according to a study by University of Chicago researchers published online for the Journal of General Internal Medicine
. But as the delay gets longer, the damages multiply. A ten-year delay decreased life expectancy by almost five months.
"For newly diagnosed patients, this means we have time," said study author Neda Laiteerapong, MD, instructor of medicine at the University of Chicago. "Most patients would prefer to control their blood pressure through diet and exercise rather than with medications, and it can take months to learn how to change old habits and master new skills. Our results indicate that it's OK to spend from six months to a year, perhaps even longer, to make the difficult lifestyle changes that are necessary and will pay off in the long run."
High blood pressure is especially damaging for people with diabetes, raising their risk of stroke, coronary artery disease, kidney failure, vision loss and amputations. Both the American Diabetes Association (ADA) and the National Institutes of Health recommend a lower blood pressure target for patients with diabetes than for the general public, urging them to keep their pressures below 130/80 mmHg.
Two out of three adults with diabetes, however, never reach that goal. Many patients are hampered by limited access to health care. Others are delayed by what the authors call "clinical inertia," a disinclination by patients to implement lifestyle changes or reluctance by their doctors to push additional medications. Among those who are prescribed
blood pressure drugs, at least 20 percent...
